Why carboxylic acids act neither like aldehydes nor like ketones based on resonance?

Feb 24, 2018

Because they are different molecules?

Explanation:

Just to retire this question, we got carboxylic acids...$R C {O}_{2} H$..versus aldehydes, $R C \left(= O\right) H$, versus ketones, $R C \left(= O\right) R$ versus alcohols, $R C {H}_{2} O H$ versus alkanes, $R C {H}_{3}$...and the oxidation numbers of the ipso carbon are....

$C {O}_{2}$ $, C \left(+ I V\right)$

$R C {O}_{2} H$ $, C \left(+ I I I\right)$

$R C \left(= O\right) R$ $, C \left(+ I I\right)$

$R C \left(= O\right) H$ $, C \left(+ I\right)$

$R C {H}_{2} O H$ $, C \left(- I\right)$

$R C {H}_{2} R$ $, C \left(- I I\right)$

$R C {H}_{3}$ $, C \left(- I I I\right)$

$C {H}_{4}$ $, C \left(- I V\right)$

Often we speak of the oxidation of carbon in organic chemistry..
